Hertel E599924526 Ball End Mill 4 Flute Solid Carbide

Product Description

The HERTEL E599924526 is a solid carbide ball end mill designed for precision milling operations in metal fabrication and machining environments. With a 0.2813-inch cutting diameter and a 0.75-inch length of cut, this tool is built for contouring, profiling, and finishing passes in tight geometries. The 4-flute configuration supports efficient chip evacuation while delivering a smooth surface finish. A 30-degree helix angle reduces cutting forces and improves tool stability at moderate to high feed rates. This end mill ships uncoated and is suited for machinists and tool-and-die professionals working in standard shop conditions.

This ball end mill is applicable to CNC milling centers and manual knee mills where small-diameter, close-tolerance work is required. The single-end design and 5/16-inch shank diameter make it compatible with standard collet chucks and end mill holders. Typical applications include 3D contouring, radius milling, cavity work, and die finishing in ferrous and non-ferrous materials. Right-hand cutting and right-hand flute direction are standard for conventional CNC spindle operation.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision milling
• 4-flute design balances chip clearance with surface finish quality
• 30-degree helix angle reduces radial cutting forces during profiling passes
• 0.2813-inch ball nose diameter enables tight-radius contouring and cavity work
• Uncoated finish suitable for use with cutting fluids on a broad range of materials
• Single-end configuration with 5/16-inch shank for standard collet and holder compatibility

Compatibility

Designed as a standard solid carbide ball end mill with a 5/16-inch shank, compatible with collet chucks and end mill holders sized for 5/16-inch shanks on CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout tolerance. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank to the recommended minimum engagement depth in the collet or holder to prevent pullout under load. Verify tool runout with a dial indicator before commencing cuts.
